Is anyone having trouble uploading to YouTube lately?

For the past month or so, I've all of the sudden been unable to upload my videos to YouTube using FireFox or Safari. They upload partially and then just stop. Sometimes they get almost all of the way there. Other times they only make it to 30% before they stop. I've tried the new uploader that claims to be resumable. I've never been able to resume a video upload. I'm using a MacBook Pro with iMovie 09. iMovie stopped being able to upload to YouTube quite some time ago. It acts like it uploads the video completely, but it's not there when you go to YouTube.

I've tried everything that I can think of. I was able to be successful using my Flip Share software as long as the video is under 10 minutes long. Although YouTube allows 15 minute videos now, the Flip Share gives an over-the-limit error when greater than 10 minutes.

I'm at my wit's end and really need to be able to upload 3 to 4 14 minute videos that are just under 800mb in size. Can anyone help me figure out what the heck is going on with this? My youtube channel is PhatFiber. You will see that I've been uploading videos for a couple of years with no problems. Please help if you can! Thanks.
